Race Setup Notes for the 3RACING 64 Pitch Spur Gear 128T

The 3RACING 64 Pitch Spur Gear 128T is built for fine ratio control and predictable tooth engagement under race conditions. Use it where small pinion changes are needed to dial lap time without upsetting driveline balance.

Installation and Mesh Guidance

Install the 3RACING 64 Pitch Spur Gear 128T with careful pinion alignment and verify endfloat. Correct mesh reduces friction and preserves motor efficiency, particularly with high RPM brushless systems.

Tuning Impact and Durability

On-track, this spur supports accurate power delivery with minimal slippage. Monitor tooth wear after heat-intensive runs and use conservative lubrication practices to maintain consistent gear life and performance.

What pinion increments work best with 128T?

Small pinion step changes are effective; try one or two teeth adjustments and log lap times to find the optimal top speed to acceleration trade off.

How to detect poor mesh during practice?

Listen for uneven tooth contact noise and inspect for point loading on teeth; these indicate mesh needs tightening or slight offset correction.

Any recommendations for high load events?

Use verified mesh settings, check gearbox bearings, and consider a slightly larger pinion only if cooling and drivetrain tolerances allow it without inducing slippage.
